followed the instructions to the T redid it a dozen time with the same result the back end of virtuemart has all its products, categories, vendor info etc. The back end has no errors. When I try and set the menu item to virtuemart front page it saves properly. When I go to front end get a HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request. no matter what categories I click on same result. Any help would be appreciated.

Just completed this 1.0 to 1.1.9 and 2.0.16 plus joom 1-1.5-2.5 pheeeewwww smooth. Hard part was jupgrade is no longer in extensions but is still on-line and free (google).

The other eek was that instructions had one migrating vm after upgrade to J 2.5 but instructions at dashhelp migrate before j 2.5 upgrade. To make it work, I had to rename jos_vm.... tables to j25_vm... then plain sailing.

Step5: Upgrade VM using this guide (http://dashhelp.com/tutorials/joomla-tutorials/75-migrate-virtuemart-1-1-9-to-version-2-0-updates) in the new Jupgrade admin folder (www.yoursite.com/jupgrade/administrator etc), in addition to following the guide in moving VM product images folder to "/var/www/yoursite/images/stories/virtuemart" folder, also create an identical copy in "/var/www/yoursite/jupgrades/images/stories/virtuemart". This image move is required before VM2.0.6 migration. If you have done the migration and did not see the image related to the product, doing the migration again will not help fix it. You will need to restart the step 5 process from last akeeba backup,(drop all database before restore, i decide to drop the DB for simplicity although only certain tables are required to be cleared)

If you still have a 1.5 site using VM 1.1.x, an easier path to full migration will be to migrate Virtuemart first, then migrate Joomla.

I am curious that you state in this post to migrate Joomla from 1.5.26 to 2.5.x first, then VM, yet the VM migration guide at Dashhelp states to migrate VM first then Joomla? Which is actually easier and more successful?

After several migration attempts through combination of methods found online, finally got a working approach that successfully migrates Joomla 1.5.x to 2.5.4 and VM1.1.x to VM2.0.6. Doing this for my future ref as well as assisting those who're still in need of a working approach for both joomla and virtuemart migration

Step0: Do this migration on a test site, before moving it to a live site after testing.

Step1: To reduce complication, I have strip Joomla of all unnecessary extension and kept only VM and Akeeba Backup in place, and selected default template that comes with Joomla original install.

Step5: Upgrade VM using this guide (http://dashhelp.com/tutorials/joomla-tutorials/75-migrate-virtuemart-1-1-9-to-version-2-0-updates) in the new Jupgrade admin folder (www.yoursite.com/jupgrade/administrator etc), in addition to following the guide in moving VM product images folder to "/var/www/yoursite/images/stories/virtuemart" folder, also create an identical copy in "/var/www/yoursite/jupgrades/images/stories/virtuemart".

thanks for this tutorial, but I have a question : if I understand correctly, I first have to perform:First: an upgrade Joomla 1.5.26 to Joomla 2.5.Then: to migrate from 2.0.x Virtuemart Virtuemart to 1.1.9Correct?

@macchu I have noticed the reversal of order, it was definitely upgrade Joomla first... but now talk is VM first. The latter may be an issue if you have more than one image per product as that utility still assumes you upgrade Joomla first. Very confusing but I have done 3 with Joomla first and two went OK. Currently doing another.

I am surprised VM developers have not written a migration script that saves all settings for import into the new install.

@Shibumi: you mean like this one? Anyway they coded a component that handle its own migration process quite well in real life (only my experience), and wrote an exact if simple howto

I managed to migrate to VM 2 (still using joomla 1.5.26) and all the images are there BUT I can't seem to be able to configure the shop from the backend... I can't select the currency... The drop down menu displays all the currencies but when I try to select a currency it doesn't work and the same things happen in the additional information with both the country and the state...

Indicates you are not logged in as Vendor yet - there is a set vendor tool at the bottom of the migration tab.

But as some VM2 functions do not work under J1.5.26 it may be better to migrate your Joomla version to 2.5.11 before setting up the store. As long as you do everything on copies of the original site then you can't lose everything.
